17. The sacred thread.
Brāhman boys are invested with the sacred thread between the ages of five and nine. The ceremony is called Upanayana or the introduction to knowledge, since by it the boy acquires the right to read the sacred books. Until this ceremony he is not really a Brāhman, and is not bound to observe the caste rules and restrictions. By its performance he becomes Dvija or twice-born, and the highest importance is attached to the change or initiation. He may then begin to acquire divine knowledge, and perhaps in past times it was thought that he obtained the divine character belonging to a Brāhman. The sacred thread is made of three strands of cotton, which should be obtained from the cotton tree growing wild. Sometimes a tree is grown in the yard of the house for the provision of the threads. It has several knots in it, to which great importance is attached, the number of knots being different for a Brāhman, a Kshatriya and a Vaishya, the three twice-born castes. The thread hangs from the left shoulder, falling on to the right hip. Sometimes, when a man is married, he wears a double thread of six strands, the second being for his wife; and after his father dies a treble one of nine strands. At the investiture the boy’s nails are cut and his hair is shaved, and he performs the hom or fire sacrifice for the first time. He then acquires the status of a Brahmachari or disciple, and in former times he would proceed to some religious centre and begin to study the sacred books. The idea of this is preserved by a symbolic ritual. Some Brāhmans shave the boy’s head completely, make a girdle of kusha or munj grass round his waist, provide him with a begging-bowl and tongs and the skin of an antelope to sit on and make him go and beg from four houses. Among others the boy gets on to a wooden horse and announces his intention of going off to Benāres to study. His mother then sits on the edge of a well and threatens to throw herself in if he will not change his mind, or the maternal uncle promises to give the boy his daughter in marriage. Then the boy relinquishes his intention and agrees to stay at home. The sacred thread must always be passed through the hand before saying the Gayatri text in praise of the sun, the most sacred Brāhmanical text. The sacred thread is changed once a year on the day of Rakshabandhan; the Brāhman and all his family change it together. The word Rakshabandhan means binding or tying up the devils, and it would thus appear that the sacred thread and the knots in it may have been originally intended to some extent to be a protection against evil spirits. It is also changed on the occasion of a birth or death in the family, or of an eclipse, or if it breaks. The old threads are torn up or sewn into clothes by the very poor in the Marātha districts. It is said that the Brāhmans are afraid that the Kunbis will get hold of their old threads, and if they do get one they will fold it into four strings, holding a lamp in the middle, and wave it over any one who is sick. The Brāhmans think that if this is done all the accumulated virtue which they have obtained by many repetitions of the Gayatri or sacred prayer will be transferred to the sick Kunbi. Many castes now wear the sacred thread who have no proper claim to do so, especially those who have become landholders and aspire to the status of Rājpūts.
